Interesting poll. Will be curious to read responces and see results. I am not voting because neither query fits me. I use the product when I have it and think i get results with root growth. If I run out I don't panic and make an emergency trip to the garden center to buy more. It is expensive and each time I buy it I think that I could be buying another orchid. I think you are going to find a wide variety of opinions with this. Should be fun or at least interesting to hear some comments and theories.
I guess what I am saying is that it is not the end all of end all/miricle of miricle products. I have never found a product for orchids or any other plant that is. The only real requirement to grow them is to love them enough to give them the basics that they require, a little secret treat known only to you the grower/custodian and then just let them grow to be themselves---the MOST beautiful flower on earth! Remember at one time they were used as packing material for items being shipped and seemed to survive that and grow again once given care.
